Native American archaeological site with 14 mi. of trails plus exhibits & ranger-led talks.
"Over 1,000 years ago, thousands of mounds of earth were constructed across parts of Iowa, Wisconsin, Minnesota, and Illinois by more than 20 different Native American tribes. At least 200 of these have been preserved and can be found at the Effigy Mounds National Monument in Iowa. Wander through one of the most beautiful places in the Upper Mississippi River Valley while trying to find recognize the animals that inspired the non-uniform mounds (think: lynx, bison, birds, and bears). Out of respect for the culture and history of this sacred site, the mounds are accessible only by foot." [Travel+Leisure]
